The primary difference between both is that abiotic factors include those components of the ecosystem which are non-living part of any habitat. On the other hand, biotic factors include living components of the ecosystem.
The examples of the abiotic factors are sunlight, the wind, clouds, water, rocks, energy, temperature, soil, etc. while the examples of biotic factors are plants and trees, animals, microorganisms such as fungi, bacteria, algae.
The ecosystem provides the major platform for the interaction between the two, as they both depend on each other for the various things chiefly biotic factors depend on the abiotic factors for fulfilling their requirements to grow and survive. To elaborate further, we will consider the few points which distinguish both the entities.

|Basis for Comparison||Abitotic Factors||Biotic Factors|
|Meaning||Abiotic factors are the non-living things of an ecosystem.||Biotic factors are the living things of an ecosystem.|
|Examples||Sunlight, temperature, energy, the wind, water, soil, etc.||Plants, trees, animals, microorganism, etc.|
|It affects||The individual of a particular species, their population, community, ecosystem and the biosphere.||The biome, individual of a particular species, biosphere, population.|
|Dependency||Abiotic factors do not depend on biotic factors for their survival.||Biotic factors depend on abiotic factors for their survival.|
|Limiting factors||Due to changes in the abiotic factors, it may sometimes limit the growth and development of a particular species or their population or |
sometimes may hamper the entire ecosystem.
|Due to any uncertain changes in particular species, may bring changes in the other species also, which directly or indirectly bank on them.
|Approach towards changes||These factors do not adapt any changes.||These factors can adapt the changes, in order to survive.|
Definition of Abiotic Factors
The abiotic factor is also known as ‘environmental factor‘. Abiotic factors and biotic factors covers the almost entire biosphere, and it is the sum covering all ecosystems. The only difference between abiotic and biotic is that abiotic factors comprise of the factors like pH, temperature, climate, humidity, soil, water, minerals, gases, light, wind, etc.
These are the non-living things, but directly or indirectly influence the growth of the biotic factors. Like for instance if there are sudden changes in the temperature of the particular ecosystem, it’s ill effect will be seen on the plants, animals and living organisms residing over there. The after-effect will be that either they will migrate from that place, or they will not be able to survive anymore, or else they may gradually adapt the changes in order to survive.
Definition of Biotic Factors
The main features which differentiate the biotic with that of abiotic factors are: they respond to the stimuli, they require energy to work, they grow and develop, they contain hereditary material like DNA (Deoxyribose nucleic acid) which are transfer from one generation to another, as well they reproduce and have the capability to give rise to the young ones.
Biotic factors largely rely on abiotic factors for their growth and survival, which can be direct or indirect. For instance, organisms living in a pond depends on the circumstances like the availability of the food and nutrients, temperature, pH, sunlight, water, etc., and if there are any changes in these factors, it would directly hamper the population of the organisms living in that pond.
Biotic factors shape up the living form of an ecosystem and comprise of:-
1. Producers or autotrophs.
2. Consumers or heterotrophs.
3. Decomposers or detrivores.
1. Producers or autotrophs: These kinds of organisms can prepare their food by their own. They prepare their food through photosynthesis like green plants, few algae, and bacteria or it can be through chemosynthesis like in few microorganisms.
In photosynthesis, the food is prepared with the help of sunlight, air, and water, whereas in chemosynthesis the organisms utilize the carbohydrates and convert into organic matter by the oxidation of inorganic compounds and thereby using this organic matter as a source of energy.
2. Consumers or heterotrophs: These are the organisms that directly of indirectly depends on the producers for their food and nutrition.
Examples are animals.
Key Differences Between Abiotic and Biotic Factors
Coming points are the key differences between the abiotic and biotic factors:
- Abiotic factors are the non-living things of an ecosystem; Biotic factors comprise of the living things of an ecosystem.
- Examples of the abiotic factors are sunlight, temperature, energy, the wind, water, soil, etc., whereas plants, trees, animals, microorganisms, etc.
- They both ( abiotic and biotic factors) may affect the individual of a particular species, their population, community, ecosystem and the
- Abiotic factors do not depend on biotic factors for their survival, but biotic factors depend on abiotic factors for their survival.
- Due to changes in the abiotic factors, it may sometimes limit the growth and development of a particular species or their population or sometimes may hamper the entire ecosystem. Whereas in biotic factors due to any uncertain changes in particular species, may cause changes in the other species also, which directly or indirectly bank on them.
- Abiotic factors do not adapt any changes whereas biotic factors can slowly adapt the changes, in order to survive.
Our biosphere consists of biome, ecosystem, community, population, and species and includes every factor present on earth. Whereas ecosystems contain the synergy between non-living (abiotic) and living (biotic) factors and covers every area whether it is a deep inside the water, in the air, or on land.
At the same time, the abiotic factors regulate the presence or survival of the particular species in that particular environment though biotic factors dependency on abiotic factors is for food, protection, shelter, or reproduction.
